776 results about "Auger" patented technology

An auger is a drilling device, or drill bit, used for making holes in wood or in the ground. It usually includes a rotating helical screw blade called a "flighting" to act as a screw conveyor to remove the drilled out material. The rotation of the blade causes the material to move out of the hole being drilled.

Loose-soft rock soil stratum reverse circulation casing-following drilling tool and drilling process

The invention discloses a loose-soft rock soil stratum reverse circulation casing-following drilling tool and a drilling process. The drilling tool is of a coaxial three-passage structure and comprises a double-wall drilling stem, an auger stem, a drilling bit, a casing and a casing shoe, a central hole of an inner tube of the double-wall drilling stem and a central hole of an inner tube of the auger stem form a slag discharging passage, an annular gap between the inner tube of the auger stem and an outer tube of the auger stem forms an air incoming passage, and an annular gap between the outer tube of the auger stem and the casing forms an outer ring passage; compressed air enters the drilling bit through the air incoming passage and then is diverted and used for assisting a cutting bladeto break a stratum and realize reverse circulation deslagging. Drillings suspended in the outer ring passage go up along spiral blades, enters a deslagging passage through a deslagging window and then returns to the ground surface. Reverse circulation deslagging through a fluid medium and deslagging assisted by the spiral blades are adopted in the process of drilling, so that casing-following drilling is realized to protect hole walls, the problems of bit burying and difficulty in deslagging and hole forming in the process of loose-soft rock soil drilling can be solved, and integration of drilling, collapse preventing, dedusting and wall protecting is realized.

Machine for mixing and distributing products used to feed livestock

A machine including a container fitted with a base that extends between lateral walls and end walls. The base partially covers (i) a mixing rotor and (ii) a feed auger which moves products in the skip either in a closed circuit or in a circuit towards a distributing chute. A transfer screw is mounted on top of the feed auger. The transfer screw can include cutting members in the form of sectioning parts. The sectioning parts co-operate with teeth which are disposed on a beam. The teeth can be positioned as necessary either on a beam located in the container or on one or more beams located on the lateral wall. Similarly, the feed auger can also include sectioning parts that co-operate with teeth if required.

Silo unloader

The silo unloader having one or more augers journaled for rotation therein is arranged to travel in a circular manner within a tower silo to auger silage to a collection point at the center thereof. Located proximate the central collection point is a transfer conveyor comprising two vertically oriented snowmobile track assemblies arranged to have corresponding flights of the track belt engaged with one another. As the tracks are driven by an electric motor, silage becomes entrained between the two adjacent tracks and is propelled therealong onto a discharge conveyor that leads to a drop chute opening in the wall of the silo.

Auger-anchored beach umbrella

An auger-anchored beach umbrella has a canopy member for supporting the canopy and a pole member for anchoring the umbrella in the ground. The canopy member has a lower tubular element within which is formed an axial lumen. The pole member has an upper element which slides snugly into the axial lumen of the canopy member. The pole member has a motor element, within which is enclosed a reversible electric motor. Coupled to the motor's shaft is an auger. The motor is electrically connected to one or more batteries and to a switch. The user inserts the pole member into the ground by activating the switch in the forward direction, thereby causing the auger to bore into the ground. In the preferred embodiment, the user grasps a handle attached to the upper element to guide the pole member into the ground and to exert a supplemental downward force on it. After the auger is firmly anchored in the ground, the canopy member is mounted on the pole member by sliding the axial lumen over the upper element of the pole member. When the beach umbrella is removed from the ground, the canopy member is removed from the pole member. The user activates the switch in the reverse direction, thereby causing the auger to disengage from the ground. In the preferred embodiment, the user grasps the handle to guide the pole member out of the ground and to exert a supplemental upward force on it.

Utility device having an improved rotatable drive mechanism

A utility vehicle or other device for excavating soil or the like includes a utility mechanism, such as, e.g., a trencher, an auger or the like, with a motor-driven utility drum. In preferred embodiments, the motor is contained substantially entirely inside the drum. Preferably, the drive shaft is operatively connected to said drum to rotate the drum at a connection location that is displaced inward from ends of said drum. In some embodiments, the drive shaft is also preferably operatively connected to a second utility mechanism, such as, e.g., a trencher chain. In some embodiments, a planetary transmission is also located inside said drum.

Harvesting machine for root-tuber crop in deep soil layer

The invention relates to a harvesting machine for a root-tuber crop in a deep soil layer. Straight growing root-tuber crops, such as Chinese yam, are almost harvested by manual operation, so that the efficiency is low and the cost is high. The existing harvesting equipment has the defects that the soil excavating depth is shallow, and the crop completeness is difficult to guarantee. The harvesting machine comprises a power device, a machine frame, spiral drilling rods, a front conveyor, a conveying bet mechanism and a soil discharging auger, wherein side baffles are fixed to the two sides of the machine frame; the spiral drilling rods are assembled at the lower part of the front section of the machine frame side by side; the front conveyor and the conveying bet mechanism are assembled on the machine frame in sequence, and are joined and matched in tandem to convey and lift the harvested crop and soil to the ground; the soil discharging auger which is connected with the spiral drilling rods and the power device transfers power and evacuates the soil below the machine frame and pushed by the spiral drilling rods backwards. According to the harvesting machine, through mechanical soil loosening and through two-stage conveying of the front conveyor and the conveying belt mechanism, the soil excavating depth is increased, the work efficiency is improved, and the labor intensity and the operation cost of the crops, such as the Chinese yam, are reduced.
